What is Potassium stearate

What is Potassium stearate ?

Potassium is also known for its alias "potassium octadecanoate". White crystalline powder. Soluble in hot water, insoluble in ether, chloroform and carbon disulfide. The aqueous solution is alkaline in comparison to phenolphthalein or litmus and the ethanol mixture may be slightly alkaline in comparison to phenolphthalein. It is made by neutralizing the reactions of stearic and potassium hydroxide. Commonly utilized in the fabrication of surfactants and fiber softeners. It can also be used in the creation of anti-slip material, graphene modified glues as well as anti-caking agents and waterproof coils.

1. . used to prepare a new kind of slip-resistant material

The latest non-slip fabric has strong wear resistance and anti-slip quality, and the materials used in the formula is organic and easy to obtain. In the production process, the process is easy and easy to operate, and the producer has an extensive and efficient material formula. Materials used in production include small fiber, short fibre, water-based glue, zinc oxide(zinc oxide), anti-aging agent, the photoinitiator, and stearic Acid. Potassium stearate, potassium stearate or coupling agent, and carbon fiber. These are calculated in accordance with its mass percentage. new non-slip material Including 5-10 parts of the long cord, 0.5-5 percent of water-based glue. of zinc oxide, 1-5 antioxidant pieces, 2-8 slices of stearic acid 1-5 components of photoinitiator Potassium Stearate 10-13 parts 1-8 parts potassium stearate, 3-10 parts of coupling agent together with 0.5-10 elements of carbon.

2 . used to prepare graphene-modified glue

The addition of graphene to the existing glue to modify the resistance to high temperatures of the cement and improve its adhesion. The material for preparing the paste is calculated by parts by weight: 12-30 parts of polyurethane, 15-30 parts of chloroprene rubber, 15-30 parts of polyacrylate, 2-12 parts of graphene, triallyl isocyanuric acid 0.8-1.6 parts of ester, 1-6 pieces of ethylenediamine, 2-10 parts of n-butanol, 2-8 pieces of toluene, 0.8-3 parts of potassium stearate, 2-8 parts of polyvinylpyrrolidone, N- 1-5 parts of phenyl-b-naphthylamine;

The specific steps are as these:

Level 1: The graphene gets added to n'butanol and toluene, the ultrasonic dispersion is uniform, in order to get a mixed solution;

Step 2, adding polyurethane, chloroprene rubber, and polyacrylate into the reactor, the temperature is raised to 80-105 deg C, the reaction is 1-3 hours, and then the mixed solution A and triallyl isocyanurate in the first step The acid ester, potassium stearate, polyvinylpyrrolidone, and N-phenyl-b-naphthylamine are sequentially added to the reactor, the reaction temperature is adjusted to 150-360 deg C, and the reaction is carried out for 2-5 hours to obtain a mixture B;

Step 3: the above reaction ceases, and the temperature is decreased to around 80 degrees Celsius. ethylenediamine is added into the reactor, stirring it evenly and then left to stand for one day before obtaining a graphene-modified glue.

3. Preparation of composite anti-caking agent for use in potassium chloride food grade

In order to lessen the chance of having hypertension, it's currently allowed to add some of potassium chloride as a replacement for sodium chloride found in the salt. But, during the process of transportation and storage for potassium chloride, the moisture contained in the product encourages breakdown and recrystallization on the powder surface, thereby forming an intergranular bridge in its pores and the crystals are combined together over time to develop. Huge mass. The weakening of fluidity influences its use in table salt. Thus, to avoid agglomeration, it's important to add a sufficient amount of anti-caking agent in the process of production.

The anticaking agent composite used in food grade potassium chloride is non-toxic harmless in its color, odor, and colorlessness. It is made up of D-mannitol as well as potassium stearate and calcium dihydrogen phosphate. the specific gravity of D-mannitol potassium stearate, as well as dihydrogen phosphate is (1.25-5): (0.1-0.4) 1. The purity of D-mannitolcompound, potassium stearate and calcium dihydrogen phosphate are food grade. In comparison to other known methods it has the advantages of being colourless or slightly white, does not change the appearance of the color of potassium chloride. It is free of cyanide, is not toxic, and is safe.

4. . The preparation of high-molecular polyethylene polypropylene waterproof membrane

Polyethylene polypropylene has become a revolutionary material used in recent years. Polypropylene is a blend of polypropylene non-woven fabric and polyethylene as the basic raw material. It is made of anti-aging compounds and created by high-tech, modern technologyand innovative technology. The polymer polyethylene polypropylene composite water-proof roll material with an integrated layer has a substantial friction coefficient, outstanding durability, stability, high mechanical strength and a small linear expansion coefficients, a large temperatures, good weather resistance, chemical resistance and flexibility. This is a desirable green environmental protection product in the current century. The procedure for the preparation of the high-molecular polyethylene polypropylene waterproofing membrane is as follows:

Step 1: Weigh the raw materials using the following parts of weight in the range of 80-130 parts polyethylene resin, 10-20 parts of Talcum powder, 5-10 pieces of silica fume. 5-10 parts that are glass beads. Also, 8-16 parts of potassium Stearate. 8-18 pieces of carboxylated styrene butadiene latex, 10-20 percent of anti-aging agents;

Step 2: Add talcum powder, silica fume along with potassium stearate as well as carboxylated latex of styrene and butadiene into high-speed mixer. Turn up the temperature to 70 to 80 deg C. Stir the mixture at high speed for 8 to 18 minutes, and then increase the heat to 95 to 100 degrees Celsius. Then, glass microbead and polyethylene resin are added, and the mixture is stirred on high speed for 10-20 mins in order to get a mixture

Step 3: Place the mixture into the feeding area Extrude and then form the sheet of polypropylene, and then the plastic sheet fully using the three-roller machine. Transfer the guide roller on the tractor, slice the edgeand then go into the coiler to get the final product.

Comparatively to the standard of the art advantageous outcomes of the invention are an effect of synergy between the polyethylene resin, quartz microbeads potassium stearate and carboxylated styrene butad latex, anti-aging agents, and any subsequent preparation steps, especially When the high-speed mixing process is being carried out with the proper order of input of ingredients is particularly vital. Together with the sequence of this invention in the present invention, the performance of made high-molecular polyethylene polypropylene waterproofing membrane outperforms that of the conventional high-performance waterproofing membrane.
